Working Principles

The AT28C64E-15SI utilizes a combination of electronic circuits and memory cells to store and retrieve data. When the chip is powered on and enabled, the address inputs are used to select a specific memory location. The data stored in that location can be read by enabling the output enable pin. To write new data, the chip must be enabled and the write enable pin activated. The data input pins are then used to provide the desired information for storage.
